JOSEPH K. SHARPE, JR., OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE INDIANAMANUFACTURING COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION OF WESTVIRGINIA.

PNEUMATIC STACKER.

Specification of Letters Patent.

Patented Aug-9, 1910.

To all whom it may concern:

Be it known that I, JOSEPH K. SHARPE, J12, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements in PneumaticStackers, of which the following is a specification.

My invention relates to improvements in pneumatic stackers, andparticularly to the chute thereof, which I so arrange as to permit theescape of a large portion of the discharging air blast before it reachesthe hood or deflector, to insure that the material will not forciblystrike the latter but will be discharged gently therefrom, and in whichchute I also provide means by which the material may be so deflected asto travel along the upper side of the hood and be discharged in acompact stream from the outer end thereof without scattering through theen tire area of the mouth of the hood which, under some conditions,would be the result when the air blast has been separated from thematerial.

In the accompanying drawings, which are made a part hereof, Figure 1, isa side elevation of a pneumatic stacker chute embodying my invention;Fig. 2, a longitudinal sectional view of said chute, and Fig. 3, atransverse sectional View on the dotted line 3-3 in Fig. 2.

In said drawings the portions marked 10 indicate the chute to which ahood or deflector, 11, of any approved character may be attached. In theupper side of said chute, I provide an opening from which I extend theinclined side and end walls, 12, 13, as indicated in Figs. 1 and 2.Preferably longitudinally of said opening I place a series of bars, orgrating, 15, for a purpose presently to be explained. At the bottom ofsaid chute I provide an adjustable deflector, 20, which may be pivotedin any suitable manner, as to a bracket, 21, and which deflector Iprovide with an arm, 22, to which a rope or cord, 23, may be attachedand passed around a sheave, 25, attached to said chute, the end of saidrope extending to a point within convenient reach of the stackeroperator. Preferably in front of said deflector 20, I provide a shield30, which overlaps the lower end of said deflector to prevent materialfrom collecting thereunder, the

latter lying normally along the bottom of the chute substantially asindicated by the dotted lines in Fig. 1.

In operation, as the material is being discharged through said chute bythe air blast, said deflector 20, may be raised or lowered by pullingupon or releasing rope 2?), the raising of which deflects the air blastupwardly and through grating 15, while the material, having beenseparated from the air and deflected toward the upper wall of the hood,flows with materially reduced speed along said upper wall and isdeposited in compact condition upon the stack, as hereinbeforeindicated.

I claim as my invention:

1. A pneumatic stacker chute having an opening in its upper sideadjacent to its delivery end for the discharge of air, a gratingspanning said outlet for preventing the escape of material therethrough,and a deflector within said chute for deflecting air through saidopening and directing the discharging material separated from the airsubstantially along the inner upper side of said chute beyond saidopening and through terial is discharged at reduced speed.

the delivery end thereof whereby said ma- 2. A pneumatic stacker chutehaving an opening in its upper side adjacent to its delivery end for thedischarge of air, walls surrounding said opening, a grating within saidwalls and spanning said opening for preventing the escape of materialtherethrough, a hood at the outer end of said chute, and a deflectorwithin said chute for deflecting air v through said opening anddirecting material separated from the air along the inner upper side ofsaid hood whereby said material is discharged at reduced speed. j,

'3.A pneumatic stacker chute having an' air discharge outlet adjacentits delivery end,

a hood at the delivery end of said chute, a

shielded adjustable deflector within said chute for directing airthrough said outlet and material through said hood, an arm attached tosaid deflector, and means connected with said arm for raising'andlowering said deflector.

4:. A pneumatic stacker chute having an air discharge outlet adjacentits delivery end,

a grating over said outlet, an adjustable d eflector in said chutearranged to deflect air through said outlet and material toward thedelivery end of said chute, and means connected With said deflector foradjusting the same;

5. A pneumatic stacker chute having an air discharge outlet adjacent itsdelivery end, Walls surrounding said outlet, a grating over said outletto permit the escape of air and prevent the discharge of materialtherethrough, an adjustable deflector Within said chute arranged todeflect air through said outlet and material along the inner upper sideof the delivery end of said chute, an arm connected to said deflector,and flexible means connected to said arm for adjusting said deflector.

In testimony whereof I aflix my signature in presence of two Witnesses.
